Enhance member management by adding postal code and contact handling

Introduced a postal code field to the member model and implemented a new MemberContact model to manage multiple phone numbers and email addresses. Updated the member service and controller to handle contact data during member creation and updates. Enhanced the MembersView component to support input for multiple contacts, ensuring better organization and accessibility of member information.
